Filed May 26, 1930 2 Sheets-Sheet 2 Patented Feb. 21, 1933 SVEN DUNEIR, OF WHEATON, ILLINOIS WATER CLOSET Application filed May 26, 1930. Serial mama.

This invention relates to water closets provided for use in railway cars and like locations, and while it will be hereinafter deg scribed as embodied in a water closet like that shown in the co-pending application of John C. Duner for U. 8. Letters Patent, Serial No. 87 5,2413, filed July 1,1929 which has matured into a Patent No. 1,845,252, it will be readily apparent that from certain aspects the invention has broader and more general application.

Toilets of this sort are ordinarily provided with a dump pan adapted to be dropped in flushing with a resultant upflow of air frequently occurring with considerable velocity, and producing a blast directed upwardly through the toilet or closet; In the co-pending application above referred to, a draft member is disclosed for sealing the closet outlet, as an incident to the flushing of the toilet. This draft member, preferably and in accordance with the disc osures of said co-pending application moves into sealing or closed position during the initial opening movement of the dump pan, and prior, to the breaking of the water seal.

The instant invention has for its principal object the construction and arrangement of the parts of a water closet of the character described which will permit the draft member to remain in full opened position when the dump pan is dumped to the end that a free open passage-way may be provided upon occasion for the flushing and cleaning of the toilet.

This invention has also .for a principal object, the provision of a water closet of the character described, wherein the draft member may optionally be operated conjointly with the dump pan, and also wherein the dump pan may be moved to an open position while the draft member remains open to facilitate flushing and cleaning of the closet.

Another important object of the invention is the provision of a watercloset wherein the dump pan is positively moved by a lever or otherwise to a dumping position, and thereafter is returned by a separately yielding or gravity device to a closed position, and also to so construct and arrange the parts that the gravity controlled operation is or may be independent of the positively induced movement. The invention contemplated in this regard a provision of a gravity returnfor the dump pan, so constructed and arranged that it may be supported in elevated position with the dump pan open, to facilitate cleaning of the toilet.

Another important object of the invention is the provision of a water closet provided with oppositely operating dump pan and draft members, controlled normally by a single manipulative device, the parts of which will be so constructed and arranged that the dump pan may be moved to dumping position by means which are independent of said control and which provide return of parts to normal position after dumping through said control. I i

Numerous other objects and advantages of the invention will be apparent-as itis better understood from the following description, which, taken in connection with the accompanying drawings, discloses a' preferred embodiment thereof. i

Referring to the drawings,

-Figure 1 is a side elevation, parts being shown in section of a railway closetembodying the present invention;

Fig. 2 isa view partially in front elevation, and partially in section, showing certain details of construction;

Fig. 3 is a transverse partial sectional view on an enlarged scale, taken substantially on the line 33 of Fig. 4; and

Fig. 4 is an enlarged detailed perspective of the connectionibetween the manually operable positive control and the dump pan shaft.

' For the vpurpose of illustrating the present invention the drawings show a closet of-the character usually provided in Pulhnan and railway cars. As shown on the drawings this closet comprises an outer stand or support 11 of usual or preferred type, which supports a closet bowl 12 at the upper end. The closet bowl 12 is provided with an outlet 13 at the bottom, this outlet being normally closed by a water containing dump'pan 14:, which is pivoted upon a shaft 15, journalled as shown 100 in Fig. 2 in opposite sides of the support 11.

The shaft 15 is embraced adjacent its lefthand end viewing Fig. 2 by one end of an arm 16, the other end of which is pivoted at 17 to an upwardly extending link 18, in turn connected at this upper end at 19 to a manually operable lever 21 pivoted at 22 to a suitable valve control of the water-flushing mechanism indicated generally at 23. Particular description of this water-flushing mechanism is not thought necessary since it forms no part of the present invention.

The shaft 15 is provided at this end beyond the arm 16 with a fixed collar 24, upon which is formed a shoulder or stud 25. Thisshoulder or stud 25 is arranged above a lug or projection 26, formed integrally with the arm 16 so that lifting of the arm through the link 18 and lever 21 will cause the projection 26 to engage the lug 25 and rotate the shaft 15 to swing the dump pan 14 downwardly from sealing to dumping positions.

The opposite end of the shaft 15 is provided with a gravity member consisting of a weight 27, which is provided with an arm 28 secured upon the end of the shaft 15 by a set screw or lock nut 29. It will be noted that the arrangement is such that the weight tends to move the dump pan up into dumping position, so that movement of the lever 24 to accomplish dumping requires lifting of the weight.

A draft member 31 is provided to close the closet outlet 32, and this draft member is oppositely movable with the dump pan, closing movement of the draft member being preferably accomplished during the initial opening movement of the dump pan. The draft member 31 is provided with arms 33, fixed respectively upon the shafts 34 arranged horizontally through bearings 35 in the base of the stand 11. The shaft 34 at the left of the closet viewing Fig. 2 is provided with a fixed "collar 36, from which an arm 37 extends upwardly, and is provided with a laterally extending pin 38. The pin 38 is adapted to engage a cam 39. The cam 39 is carried by an arm 41 clamped about a sleeve extension 42 of the arm 16, so that the cam moves with the arm 16, and independently of oscillation of the shaft 15, except when the projection 26 in its movement causes conjoint shaft movement through the lug 26. Particular description of the cam 39 and its connection with the arm 37 is not thought necessary since it is fully explained in the co-pending application already mentioned.

From the foregoing it will be apparent that normally the draft member moves concurrently and opposite to the pan in dumping, When, however, it is desired to arrange the dumping pan in dumping position with the draft member remaining in open position, it is only necessary to lift the gravity member or weight 27 to the elevated posiit will be apparent that various changes may be made in the form, construction and arrangement 0f, the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages,

the form hereinbefore described being merely a preferred embodiment thereof.
